BROCKVILLE – Another round of heavy rain is expected to start tonight (Thursday) and carry on right through the weekend.

Environment Canada issued a rainfall warning this afternoon for Leeds-Grenville with 30-50 millimeters (1.18-1.96 inches) expected over the next three-and-a-half days.

A weather system is expected to “stall over the region” for the next three days leading to the long period of rain.

Local conservation authorities are already warning about localized flooding in low-lying areas.

The Cataraqui Region Conservation Authority has a flood watch in effect. They are also warning residents to stay away from the Buells Creek Reservoir (detention basin) in Brockville as well as Buells and Butlers Creek.

CRCA is anticipating 40-70 millimeters of rain (1.57-2.75 inches) through Sunday, on top of the 50-70 millimeters (1.96-2.75 inches) already on the ground this week.
